,HEAT-DEFLECTION SHIELD.

Application filed September 8, 1926. SerialNo. 134,169.

' heatrays are conserved and concentrated on any desired spot adjacent to the heater in the room. My invention comprises improvements. on the construction shown in my former Patent #l,'l55,551, whereby the ease of adjustabiiity of the general type of device shown therein is increased. My new invention eliminates the necessity for any clamps and springs. To adjust any of the embodiments shown therein it is merely necessary to grasp the shield and move it to the desired new position without the necessity of smieezin the clamps employed in my former construction. The preferred embodiments oi? my present invention eliminate the necessity oi any means for gripping the hall and holding the hood in any desired position,

the embodiments being so constructed that the weight or the hood alone acting through the "force of gravity will retain the hood in any desired angular position at any desired degree of tilt. Another object or my invention is to provide a simple practical and comparatively inexpensive deflection shield which can be readily adjusted to fit any type of existing heating units.

These and such other objects of my invention as may hereinafter appear will be best understood from a description of the embodiments thereof shown in the accompanying drawings. p

In the drawings, wherein like characters of reference indicatelike parts throughout, generally indicates any suitable type of upright heating unit, which may consist otan oil heater, a coal stove, radiator, electric heater, or any suitable type, as illustrated in. my Patent .tc1,l55.55l. 22 generally indicates the heat deflecting hood 012.1113 inven tion. Whereas a tray shaped hood is shown, it is understood that a dome shaped hood, as shown in my prior patent, or any other type of hood. or plate may be employed. 2% generally indicates the hood support. .My invention peculiarly relates to'the construction of the hood support 24; and'the hood 22, whereby the hood may be more readily adjusted than hitherto. I so construct these devices that the hood 22 may be readily adjusted as shown in Fig. 2 at any different angular position relative to the centre of support and may be readily tilted from a horizontal plane as shown in Fig. 1 in dotted lines in a single plane at any degree of tilt up to substantlally 45 to the horizontal. These characteristics of my invention are common to all the embodiments shown. Therefore all it is necessary to do to adjust any of my embodiments is to grasp the hood, move it to the desired angular position and tilt it at the desired degree of tilt when it will permanently remain in that position.

Having generally described the common characteristics of the various embodiments of my invention, I will now describe in detail each embodiment. The support 2% is of the same general type as the support shown in my Patent 21,455,551 and preferzbly comprises a plurality of radially spaced rods 30 as shown in Fig. 1 terminating in the hooks 32 adapted to fit underneath the cover of the heating unit 20, the lower end of one rod 30 terminating in the spring catch =82 where by the tripod formed by said rods may be readily removed from the heating unit as explained in detail in my former patent. in the embodiment shown in Figs. 1 l the upper ends of said rods are attached together so as to form a support having a substantially semi-spherical upper surface 36 of substantial area. In the embodiment shown in Fig. 1, the upper ends of the rods are first soldered as at 38, the upper end of one of said rods 30 projecting upwardly from said support. in order to form a substantially semi-spherical upper surface of substantial area, I preferably mount the hollow ball on said rod 40 above the soldered portion 38. Though it is obvious that, if desired, as shown in Figs. 5 and 6 the upper ends of said rods 30 may be soldered toget ier as to form the substantially semi-spherical upper surface 36 of sub stantial area. .418 stated, the surface 36 of substantial area is preferably roughened as at 28 for a purpose to be described.

A. heretofore stated, I preferably construct the hood 22 itself so that it maybe readily adjusted on the support- 2%. To this end as shown in Figs. 1- l, I provide on said hood a central support engaging slot :46 extending a distance from approximately the centre of the hood to limit the tilting movement of the hood 22 to a single plane. ie central portion of the hood adjacent said slot es is roughened as at 26 for a purpose to be described. The hood may be provided with a lifting handle 48. In my preferred embodiment the width of the slot as is slightly greater than that of the up *ardly projecting portion of the rod 40 of the support 2-; and said slot 46 terminates at one end 50 at approximately the centre of the hood and in the opposite end 52. it is thus apparent that if it is desired to adjust the hood in any desired angular position relative to the centre of the support that the hood may be merely lifted up by the handle 18 and adjusted to any desired angular position relative to the centre of the support, such as from the angular posi tion shown in Fig. 2 to the angular positions shown in dotted lines'therein. it is also apparent that the shape of the hood 22, the upper portion of the support 2% and the length of the slot are such that when the projecting portion {ill of the support abuts the end 50 of the slot near the centre of the hood said hood may rest on said support in a substantially horizontal plane as shown in dotted lines in Figs. 1 and 2. It is also apparent that when said hood is tilted so that the projecting portion of the support abuts the opposite end 52 of the slot to, said hood may be tilted at an angle at substantially d5 to the horizontal. it is also apparent that when the hood is tilted so that the projecting portion i0 is opposite the intermediate portions of said slot l-(i, said hood may rest at any desired intermediate tilted position between the horizontal and 45, the co-operating roughened portions 26 on the hood 22 and 28 on the surface 36 of the support functioning to interen age to permit the weight of the hood alone to retain the hood in any desired tilted and angular position. It is thus obvious that if it is desired to adjust the position of the hood it is merely necessary to lift up the hood and reset it in any desired angular and tilted position, where the force of j 'avity acting through the weight of the hood wrl cause it to remain in said set position. desired, the roughened portions 28 on the surface 36 of the support may be dispensed with or the roughened portions 26 on the hood may be dispensed wit The embodiment shown in Figs. 5 and 6 is identical to the embodiment shown in Figs. ll with the exception that the hollow ball spenscd with, the upper portion of the portion 38 soldering the upper ends of the rods 30 together being shaped to form the substantially semi-spherical upper surface 86 of substantial area.

The embodiment shown in Figs. 7-8 functions on a similar principle. In this embodiment, however, in place of the co-operating irojection 4-0 on the support and the coop crating slot on the hood to limit the tilting movement of said hood to asingle plane, 1 preferably so shape the hood 22 that it will have the centre support engaging portion 416 projecting upwards therefrom in a mound shape, the interior thereof being pressed out and of a diameter approximately equal to he substantially semi-spherical upper surface 36 of the support to lim t the tilting movement to a single plane. In this emsingle plane.

that the soldered portion bodiment also the surface 360i the support is preferably provided with the corrugations or roughened portions28 and the central support engaging portion 46 of the hood with the co-operating corrugations or roughened portions- 26 which may interengage to retain the hood in tilted position at any desired intermediate position ot'the support enfiatt'enasat 56 thecentral portion of the hood, providing it with the ridge 58 stamped therein extending from approximately one side or the flat portion 56'to the other as shown in Fig; 10. In the embodiment shown in Figsf9l2, the support 'is constructed so 38 is in a shape of a ball having the vertical diametric hole 59.

l The upper portion of the pintlerod 60 provided with the rod 62 the support comprises "integrally dependingfrom the centre thereof. The-pint-le rodis inserted within the ridge 580i the hood and clamped'thereto by -means of the hinge clamp 64: through the mediu'mot the screws 66. The hinge clamp Get is so constructed that the central slot68 thereof iso'nly of a width slightly greater "than that ot the depending rod 62 0t the hood =relative to I tive position on the ridge 58 depending on pintle rod 60 so that the tilting movement otthe'hood may be more'readily single plane as in my preferred embodiment.

limited to a lltis'thus obvious thatthe hood may be tilted at any desiredtilted position by moving the the pintle'rod 60 of the support, the pintle rod assuming any desired relathe degree'ot tilt, and the hinge clamp 64 serving't-o' trictio'nally retain the hood22 in any desired tilt-ed position. It is obvious that it"it be desired to move the hood to a diiierent angular position the hood may be adjusted sothat the rod62depending thererelative angular from may assume a different position in the vertical hole59 of the sup p'ort'Q. i

The embodiment shown in Fig. 13 shows a type othin'ge which functions on thegrav- 1 ity principle of the embodiments illustrated in'ld igs. 1 8. Inthisembodiment the upper surface of the-p'intle' rod 60 is corrugated or roughened as at 28 and the cooperating ridge or central support engaging portion -46 is similarly corrugated or roughened. as

- at"26. The hinge clamp tl atitwill n'otbear against the base of the 6 is so constructed -pintle' rod 60=to clamp saida'od 60 against the ridge 58, but is spaced therefrom so that the hood may be lifted and tilted at any desired angular position to permit 7 the force oti gi-avityacting through the weight of the hood22 to cause the 00-01 crating roughened portions 26and28 torinterengage to permit the weight of the hood alone to retain the hood in any desired tilted position, the hinge clampfii serving as a 'gaide.

It is thus obvious that I have provided a device 01": this'description more tacile of adjustment and simpler than any produced hitherto.
